To all whom it may concern:

Be it known that I, RICHARD WV. AMos, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Processes for the Disposition of Garbage, Sludge, and like Substances, of which the following is a specification.

This invention relates process and apparatus for the disposition of garbage, sludge, and like substances.

By my invention I .take a certain quantity or charge ofgarbage, consisting of vegetable or dead animal matter and other like substances and treat the same with a suitable chemical, which when heated and agitated, as hereinafter described, will release the vapors of ammonia, alcohol and phosphoric acid gas.

Figure 1 is a vertical section of an apparatus suitable for the carrying out of my process; and Fig. 2 is a front elevation of .I preferably so treat the material with powdered calcium oxid orlime, then charge with the material so treated, through a charging pipe A a suitable tank or retort A containing suitable. agitating means, such as the arms a mounted on a suitable shaft a operated by any suitable source of power, not shown. This tank is then heated by any suitable means, preferably by means of the furnace B To mass should be heated to a temperature of approximately 225 Fahrenheit. Upon such heating and agitation the vapors .of alcbhohammonia and phosphoric acid gas are driven off and separated by suitablemeans. As shown, I provide a reservoir D which is provided with a perforated plate cl,

on top of which plate is placed a suitable quantity ofpowdered chemical, preferably composed of two parts of lime to one part of nitrate salt. Such nitrate salt is preferably obtained from the gun-powder mills in the form of refuse, and is composed chiefly of sodium chlorid, sodium nitrate, potassium nitrate and potassium sulfate. In this refuse this salt is impure, that is to say, it is combined withcertain other ingredients but it serves my purpose equally as well, which purpose at this particular step of the process is toform with the lime a:

to improvements 'in' procure the best results theclarifying'and. filtering bed on the perforated plate for the ammonia liquors.

The three gases, to wit: vapors of amm'onia, alcohol and phosphoric acid are simultaneously driven ofl through a pipe A which is led through the reservoir D and the nozzle or mouth of which extends below said perforated plate (Z. When these gases are driven through said pipe the vapors of alcohol condense in the chamber .below the perforated plate (Z and may be tapped through a suitable pipe (Z provided with a suitable flange (Z The vapor of ammonia rises through the perforated plate (Z and through the powdered chemicals forming a bed on the top of the same and passes through the pipe D and through the condensing coil. D to a suitable discharge pipe D I preferably run these ammonia liquors into a tank containing sulfuric acid, so as to form a solution of ammonium sulfate which when evaporated gives ammonium form of a salt suitable for use as a fertilizer. I may, however, pass this ammonia liquor into nitric acid or other suitable combining agent to produce other suitable ammonium compounds. lVhen the vapors from the 'pipe A arise through the powdered chemicals in the reservoir D, the said lime and nitrate salts absorb the phosphoric acid and form a phosphate of lime, which may thereupon be removed from the reservoir or separating tank and used for fertilizer or any other suitable use.

aving driven off, by heat and agitation all the vapors of ammonium and'alcohol, as well as the phosphoric acid that is possible to be driven off from the charge con-,

two parts calcium oxld and two parts of the nitrate salts aforesaid. lVhen this mixture is fed into the furnace B a perfect combustion is obtained and the ash from the same contains a very large percentage of from which the potash is readily separable,

following proportions to sulfate of potash,

which comprises the treating of a suitable quantity of garbage with lime, heating the same to drlve. off the vapor contents thereof andthen separatlng' the llghter from the heavier vapors. i

2. The process of garbage dispositionwhich comprises the treating of a suitable quantity of garbage with lime, charging a suitable tank with such material, heating the tank to drive off the vapor contents'there'of and conducting such vapors to cause the lighter vapors to pass through a bed of material havlng lime as its characteristic com ponent.

i 5. The process of treating 3. The process of garbage disposition which comprises the treating of a suitable quantity of garbage with lime, charging a suitable tank with such material, heating the tan'k to gdrive olfthe vapor contents 1 thereof, conducting such vapors to cause the lighter vapors topass through a bed of material having lime as its characteristic component, condensing .the heavier'vapors and permitting the same to be tapped ofi without passing through such beid.

4. In a'process for the disposition of garbage, the "step of adding a mixture having a nitrate salt and lime asits principal ingrediex ts to a charge of garbage from which the volatile matter has been removed to form a combustible material.-

garbage from ,which the volatile matter. has been removed with a mixture having nitrate salt and lime as its principal ingredients (to form a combustible material and thelyburning such material.

6. The processof'garbag'e disposal, which consists in subjecting to heat a charge of Having described my mventionI claim 1. The process of garbage disposition {acharge of material to drive 'ofilvolatile matter,- then adding a mixture having a nitrate salt and lime as its principal ingredients to the residue and then burning such residue.

7. The process of forming a combustible material, which comprises, first, subjecting a charge of garbage to heat to drive off all volatile matter and second, mixing the residue with-a mixture having a nitrate salt and lime as its-principal ingredients.

8. The process of garbage disposition which comprises, first, treating a suitable charge of material with powdered lime, then 1 subjecting said'charge to heat in a suitable tank or retort to drive off the vapor conthe heaviervapors, removing the residue from the retort, mlxing the residue with a tents thereof, separating the. lighter from mixture havingla nitrate salt and lime as. its v principal components and then burning the mixture so *formed to heat a succeeding charge. 4

9. The process 0f garbage disposition which comprises, first, treatlng a suitable charge of material with powdered lime,

then subjecting said charge to heat in a suitable tank or retort to drive off the vapor contents thereof, separating the lighter from the heavier vapors, removing the residue from the retort, mixing such residue with a 'mi xture composed of sulfur, lime and ni-' trate salts, and then burning the mixture so formed to heat a succeeeding charge. p

The process of garbage disposition [which comprises,- first, treating" a suitable charge. of material with powdered lime, then subjecting said charge to heat in a suitable tank or retort to drive off the vapor contents thereof, separating the lighter from vthe heavier vapors, removing the residue from the retort, mixing such residue with a mixture composed of one part of sulfur, two
